Hi,

Knowledge Consistency Checker is the process which automatically generates replication topology between domain controllers in an organization. If you want to modify existing replication topology, then you could modify existing Site Connection Objects or manually create new Site Connection Objects. KCC will not modify customized or newly created Site Connection Objects. Following articles discusses how to create new site connections manually.

It will not be a good idea to stop KCC as it will be monitoring for lose of connectivity between sites and create new site connection for replication to work fine. If it is disabled, AD replication may not work properly. Following article shows how KCC can be disabled in Windows 2000/2003.

You can use the following command to force a domain controller to calculate inbound replication topology and report for any errors.

repadmin /kcc

Concepts are same for Windows 2008/2012. Please refer following article for more information.

Please check in the following location. I feel you are looking inside a server object and that setting is to make DC, GC.

Following are the values for Option. If it is not set then KCC will be running normal.

¿To disable automatic intra-site topology generation, use value 1 (decimal).
¿To disable automatic inter-site topology generation, use value 16 (decimal).
¿To disable both intra-site and inter-site topology generation, use value 17 (decimal).
